Definitions

  • the present invention relates to methods and arrangements in a mobile telecommunication network, and in particular to report transmit power headroom in conjunction with simultaneous transmission of physical uplink shared channels and physical uplink control channels.
  • LTE Long Term Evolution
  • 3GPP 3 rd Generation Partnership Project
  • LTE specifications provide downlink peak rates up to 300 Mbps, an uplink of up to 75 Mbit/s and radio access network round-trip times of less than 10 ms.
  • LTE supports scalable carrier bandwidths from 20 MHz down to 1.4 MHz and supports both FDD (Frequency Division Duplex) and TDD (Time Division Duplex).
  • LTE uses OFDM (Orthogonal Frequency Division Multiplex) in the downlink and DFT (Discrete Fourier Transform)-spread OFDM in the uplink.
  • OFDM Orthogonal Frequency Division Multiplex
  • DFT Discrete Fourier Transform
  • the basic LTE downlink physical resource can thus be seen as a time-frequency grid as illustrated in figure 1, where each resource element corresponds to one OFDM subcarrier during one OFDM symbol interval.
  • resource allocation in LTE is typically described in terms of resource blocks, where a resource block corresponds to one slot (0.5 ms) in the time domain and 12 contiguous subcarriers in the frequency domain. Resource blocks are numbered in the frequency domain, starting with 0 from one end of the system bandwidth.
  • Downlink transmissions are dynamically scheduled, i.e., in each subframe the base station transmits control information about to which terminals data is transmitted and upon which resource blocks the data is transmitted, in the current downlink subframe.
  • This control signaling is typically transmitted in the first 1 , 2, 3 or 4 OFDM symbols in each subframe.
  • a downlink system with 3 OFDM symbols as control is illustrated in figure 3.
  • LTE uses hybrid-ARQ, where, after receiving downlink data in a subframe, the terminal attempts to decode it and reports to the base station whether the decoding was successful (ACK) or not (NAK). In case of an unsuccessful decoding attempt, the base station can retransmit the erroneous data.
  • Uplink control signaling from the terminal to the base station consists of hybrid-ARQ acknowledgements for received downlink data; terminal reports related to the downlink channel conditions, used as assistance for the downlink scheduling; scheduling requests, indicating that a mobile terminal needs uplink resources for uplink data transmissions.
  • the L1 /L2 control information (channel-status reports, hybrid- ARQ acknowledgments, and scheduling requests) is transmitted in uplink resources (resource blocks) specifically assigned for uplink L1 /L2 control on Physical Uplink Control Channel (PUCCH).
  • uplink resources resource blocks
  • PUCCH Physical Uplink Control Channel
  • these resources are located at the edges of the total available cell bandwidth.
  • Each such resource consists of twelve "subcarriers" (one resource block) within each of the two slots of an uplink subframe.
  • these frequency resources are frequency hopping on the slot boundary, i.e.
  • one “resource” consists of 12 subcarriers at the upper part of the spectrum within the first slot of a subframe and an equally sized resource at the lower part of the spectrum during the second slot of the subframe or vice versa. If more resources are needed for the uplink L1 /L2 control signaling, e.g. in case of very large overall transmission bandwidth supporting a large number of users, additional resources blocks can be assigned next to the previously assigned resource blocks.
  • the mobile terminal To transmit data in the uplink the mobile terminal has to been assigned an uplink resource for data transmission, on the Physical Uplink Shared Channel (PUSCH).
  • PUSCH Physical Uplink Shared Channel
  • the assignment In contrast to a data assignment in downlink, in uplink the assignment must always be consecutive in frequency, this to retain the signal carrier property of the uplink as illustrated in figure 5.
  • the middle SC(Single Carrier Frequency Division Multiple Access (FDMA))- symbol (also referred to as DFT-spread OFDM), in each slot is used to transmit a reference symbol. If the mobile terminal has been assigned an uplink resource for data transmission and at the same time instance has control information to transmit, it will transmit the control information together with the data on PUSCH.
  • FDMA Single Carrier Frequency Division Multiple Access
  • Uplink power control is used both on the PUSCH and on PUCCH.
  • the purpose is to ensure that the mobile terminal transmits with sufficient power, but at the same time not be too high, since that would only increase the interference to other users in the network.
  • a parameterized open loop combined with a closed loop mechanism is used. Roughly, the open loop part is used to set a point of operation, around which the closed loop component operates. Different parameters such as targets and partial compensation factors for user and control plane are used.
  • the mobile terminal sets the output power according to >101og I0 (M PUSCH PUSCH U) + a - PL + A TF (i) + /(») ⁇
  • ⁇ CMAX is the configured maximum transmit power for the mobile terminal
  • PUSCH is the number resource blocks assigned, O USCH O
  • PL is the estimated pathloss
  • ⁇ ⁇ ( ⁇ ) is transport format compensator
  • /(/ ' ) is the a UE (User Equipment) specific offset or 'closed loop correction' .
  • the function f may represent either absolute or accumulative offsets.
  • the closed loop power control can be operated in two different modes either accumulated or absolute. Both modes are based on a TPC (Transmit power command) which is part of the downlink control signaling.
  • TPC Transmit power command
  • the closed loop correction function is reset every time a new power control command is received.
  • the power control command is a delta correction with regard to the previously accumulated closed loop correction.
  • the base station can filter the mobile terminals power in both time and frequency to provide an accurate power control operating point for the mobile terminal.
  • KpuscH subframe before the current subframe and f(i - ⁇ ) is the accumulated power control value.
  • the accumulated power control command is reset when changing cell, entering/leaving RRC active state, an absolute TPC command is received, P 0 PUCCH is received and when the mobile terminal (re) synchronizes.
  • the base station has the possibility to request a power headroom report from the UE for PUSCH transmissions.
  • the power headroom reports inform the base station how much transmission power the UE had left for the subframe i.
